Solar Activity

Solar activity was low this week. There are currently 6 active regions on disk with active regions 11596 and 11600 to rotate in following days.

How many GOES flares occurred?

 Flares above B, C, M, X class were     12    19     0     0

And how many of these are listed in the RHESSI flare list?

 Flares above B, C, M, X class were      7    14     0     0

And how many had EXCELLENT coverage?

 Flares above B, C, M, X class were      4     3     0     0

There were RHESSI flares/GOES flares 157 / 31 over the time range 24-Oct-12 31-Oct-12

Memory Management

Due to hurricane Sandy, 3 passes of Wallops where lost, making the SSR fill level to reach ~60%.

Spacecraft Status

The cold plate 2 is at 104.2 K respectively. Cryopower 71 W.

Spin 14.8

Data Gaps

Detector issues

G8 is continuing to show a very slow decay in emerging from night +SAA passes. The HV was lowered by 5 counts on October 24 at about 21:09UT. The voltage now sits at 3455.9 V. It seems the detector is getting noisier.

There were a couple of spike in all detectors on 28-Oct-2012 at about 12:25, 17:30 and 17:40, lasting for just a couple of minutes.
